MOUNTAIN TREES 



pressure that when the ripe berry is 

 jarred from its hold an explosion takes 

 place, shooting the seed with its mucil- 

 aginous pulp out into the air. Records 

 are given of seeds being thus shot to a 

 distance of 13 feet, and wherever they 

 land they stick. Put a sticky seed on 

 your skin or clothes and see how diffi- 

 cult it is to rub off. 



Birds feasting on these berries get 

 their bills covered with the gummy 

 seeds and in trying to clean them off by 

 wiping them on the bark of trees, dis- 

 tribute the seeds. The viscid pulp soon 

 hardens affording a protection to the 

 seed.
